Application filed October 28, 1909. Serial No. 525,073.

To all whom it may concern:

Be it known that I, CHESTER A. HAHN, citizen of the United States, residing at Collegeview, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in Automatic Gates, of which the following is a specification.

This invention relates to automatic gates and has for its object to provide a strong, durable and thoroughly efficient gate of this character, the construction of which is such that the same may be opened or closed from either side of a roadway.

A further object is to provide a swinging gate, the hinge of which is formed of a plurality of sections having interengaging faces, said sections being so arranged that when the upper section is disengaged from the intermediate section, the gate may be swung in one direction and when the intermediate section is disengaged from the lower section, the gate may be swung in the opposite direction.

A still further object is generally to improve this class of devices so as to increase their utility, durability and efficiency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for efi'ecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure l is a perspective view of an automatic gate constructed in accordance with my invention; Fig. 2 is a detail vertical sectional view of the same; Fig. 3 is a side elevation of the hinge member showing the upper section thereof partially elevated preparatory to swinging the gate in one direction, a detail horizontal sectional view of the standard being shown immediately below the same; Fig. 4 is a detail side elevation showing the intermediate hinge section partially disengaged from the lower hinge section preparatory to swinging the gate in the opposite direction, a detail transverse section of the gate being shown immediatel below the same; Fig. 5 is an enlarged detail side view partly in section of the hinge member showing the upper section thereof partially separated from the intermediate section; Fig. 6 is a detail perspective view of the operating levers; Fig. 7 is a detail perspective view of the free end of the gate showing the construction of the springlatch.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The gate comprises an upright or standard 5 disposed on one side of the roadway and having its lower end secured in any suitable manner to a supporting block or base 6, the latter being embedded in the ground, as shown. Pivotally mounted for swinging movement on the standard 5, is the gate proper, the latter being preferably formed of gas pipe or angle iron and having its longitudinal bars 7 and end bars 8 connected by iron bars or woven mesh wire 9. The rear end bar 8 is extended vertically above the upper longitudinal bar 7 to form an extension 10, to the upper end of which is fastened a bracket 11 having its intermediate portion formed with a circular socket 12 for the reception of the standard 5, there being anti-friction balls interposed between the socket 12 and standard 5 to reduce friction between the parts. Mounted on the front or short bar 8 of the gate, is a spring latch 13 having its upper end rigidly secured to the bar 8 and its lower end extended through a suitable keeper 1 1 and spaced from the adjacent face of the bar 8 for engagement with a catch or keeper 15. The catch or keeper 15 is fastened in any suitable manner to a stop post 16 and is provided with a square recess 17 adapted to receive the free end of the latch 13 for the purpose of locking the gate in closed position when the gate is swung laterally either to the right or to the left.

Mounted on the standard 5 at the lower portion thereof, is a hinge, the latter being preferably formed in three sections 18, 19 and 20 having interengaging faces or teeth 21, forming in effect a clutch. The upper section 18 of the hinge is loosely mounted on the standard 5 and is rigidly secured to the adjacent end bar 8 of the gate by means of strap irons 22, while the intermediate section 19 is loosely mounted on the standard 5 and is provided with oppositely disposed teeth for engagement with the teeth on the upper and lower members 18 and 20, as shown, the lower section 20 being keyed or otherwise rigidly secured to said standard.

Secured to the upper end of the standard V5, is a horizontally disposed arm 23 having a central socket 24 for the reception of the standard 5 and provided with oppositely disposed laterally extending pins 25 on each of which is pivotally mounted for tilting movement a pair of operating levers 26 and 27. The operating members 26 and 27 are preferably in the form of bell crank levers, to the short arms of which are pivotally mounted at 28, tubular guiding members or sleeves 29. Extending from one pair of operating levers 26, is a rod or cable 30, the lower end of which is pivotally connected at 31 to a sleeve or collar 32 loosely mounted in a seating recess 33 in the intermediate hinge section 19. A similar connecting rod 34 forms a connection between the opposite pair of levers 27 and a similar collar 35 mounted in a seating recess in the upper hinge section 18. Pivotally mounted at 36 to the connecting rods 30 and 34, are relatively short rod sections 37, the latter being slidably mounted in the adjacent sleeves 29 and provided with terminal heads 38 to prevent said rods from being withdrawn from the sleeves when a tilting movement is imparted to the operating levers. Fastened to the long arms of each set of levers 26 and 27, are operating cords or cables 39, which latter extend over rollers or pulleys 40 depending from cross bars 41 mounted on the upper ends of the adjacent uprights or posts 42. The cords or cables 39 terminate in finger pieces 43, by pulling which, the operator may open or close the gate from either side of a roadway.

In order to impart a swinging movement to the gate, suitable spring pressed pawls 44 are provided, one of said pawls being mounted for sliding movement in a recess 45 in the active face of the intermediate hinge section 19 and a similar pawl being mounted in a recess formed in the active face of the lower hinge section 20, there being stop shoulders 46 formed on the pawls 44 for the purpose of limiting the inward movement thereof. Interposed between each pawl 44 and the end of the recess 45, is a coil spring 47 which serves to force the pawl 44 outwardly beneath the adjacent tooth 21 when the active faces of the hinge members are separated, said pawl serving to direct the teeth on one member into engagement with difierent teeth on the mating member, the inclined faces of the teeth causing a partial rotation of the gate when said hinge members are brought together.

lVhen the hinge sections are brought together, the teeth at the active faces of the sections will bear against the free ends of the pawls and press the latter inwardly against the tension of the springs 47 so as to house the pawls within the recesses 45 and thus permit the active faces of the hinge sections to contact with each other.

If it is desired to swing the gate to the right, the operator exerts a longitudinal pull on the finger piece 43 which tilts the adjacent lever 27 and through the medium of the rod 34, disengages the teeth of the upper hinge section 18 from the teeth of the intermediate section 19 and at the same time elevates the gate so as to disengage the latch 13 from the keeper 15. As soon as the upper section 18 is disengaged from the intermediate section 19, the spring 47 of the pawl 44 on the intermediate section will force said pawl beneath the adjacent tooth on the upper section and thus direct the teeth on said upper section into engagement with different teeth on the intermediate section, with the result that when he fingerpiece 43 is released the inclined faces of the teeth will cause a partial rotation of said gate, a suitable stop 49 being provided for limiting the swinging movement thereof. hen the finger piece 43 on the opposite side of the gate is operated, the lever 26 will be tilted so as to cause the rod 30 to elevate the sections 18 and 19 and consequently disengage the latch from its keeper 15. As soon as the lower active face of the intermediate section 18 clears the teeth on the lower section 20, the spring 47 will force the pawl 44 carried by the lower section 20 beneath the adjacent tooth on the intermediate section 19 and cause the teeth on said intermediate section to engage different teeth on the lower section, thus to rotate saidintermediate section together with the upper section 18 and gate in the opposite direction until the latter contacts with a corresponding stop 49.

It is obvious that the gate may be opened or closed by exerting a longitudinal pull on the finger pieces 43 on either side of the gate, and that when the gate is in engagement with either stop 48 or 49, said gate may be quickly closed by repeating the operation above set forth.

Attention is here called to the fact that by making the hinge in sections and providing said sections with interengaging faces, said hinge serves to assist in locking the gate in either opened or closed position.

A diagonally disposed brace 50 is preferably interposed between the upper bar 9 of the gate and the extension 10 for the purpose of reinforcing and strengthening said gate when the latter is moved to open and closed position. Suitable anti-friction balls are also preferably carried by the hinge sections 18 and 19 for bearing against the standard 5 for reducing friction between the parts.
